Cuphea plant named ‘Magenta Border’

ABSTRACT

A new and distinct cultivar of  Cuphea  plant named ‘Magenta Border’, characterized by its compact and mounding growth habit; freely branching habit; freely flowering habit; relatively large red purple-colored flowers; and good garden performance.

Botanical designation: Cuphea hyssopifolia.

Cultivar denomination: ‘MAGENTA BORDER’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Cuphea plant, botanically known as Cuphea hyssopifolia and hereinafter referred to by the name ‘Magenta Border’.

The new Cuphea plant is a product of a planned breeding program conducted by the Inventor in Cranbourne, Victoria, Australia. The objective of the breeding program is to create new compact Cuphea plants with numerous attractive flowers and good garden performance.

The new Cuphea plant originated from an open-pollination during the spring of 2004 in Cranbourne, Victoria, Australia of an unnamed seedling selection of Cuphea hyssopifolia, not patented, as the female, or seed, parent with an unknown selection of Cuphea hyssopifolia as the male, or pollen, parent. The new Cuphea plant was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated open-pollination in a controlled greenhouse environment in Cranbourne, Victoria, Australia during the spring of 2005.

Asexual reproduction of the new Cuphea plant by cuttings in a controlled greenhouse environment in Cranbourne, Victoria, Australia since the spring of 2005, has shown that the unique features of this new Cuphea plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Cuphea have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Magenta Border’. These characteristics in combination distinguish ‘Magenta Border’ as a new and distinct cultivar of Cuphea plant:

-   -   1. Compact and mounding growth habit.     -   2. Freely branching habit.     -   3. Freely flowering habit.     -   4. Relatively large red purple-colored flowers.     -   5. Good garden performance.

Plants of the new Cuphea can be compared to plants of the female parent selection. Plants of the new Cuphea differ from plants of the female parent selection in the following characteristics:

-   -   1. Plants of the new Cuphea are more mounding than and not as         upright as plants of the female parent selection.     -   2. Plants of the new Cuphea are shorter than plants of the         female parent selection.     -   3. Plants of the new Cuphea have darker red purple-colored         flowers than plants of the female parent selection.

Plants of the new Cuphea can also be compared to plants of the Cuphea hyssopifolia ‘Southern Border’, disclosed in a U.S. Plant Patent application filed concurrently. In side-by-side comparisons conducted in Cranbourne, Victoria, Australia, plants of the new Cuphea differed from plants of ‘Southern Border’ in the following characteristics:

-   -   1. Plants of the new Cuphea were more compact than plants of         ‘Southern Border’.     -   2. Plants of the new Cuphea were slower growing than plants of         ‘Southern Border’.     -   3. Plants of the new Cuphea and ‘Southern Border’ differed in         flower color as plants of ‘Southern Border’ had purple-colored         flowers.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Cuphea plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Cuphea plant.

The photograph on the first sheet comprises a top perspective view of a typical flowering plant of ‘Magenta Border’ grown in a container.

The photograph on the second sheet is a close-up view of typical flowers of ‘Magenta Border’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the summer and autumn in 15-cm containers in a polyethylene-covered greenhouse in Cranbourne, Victoria, Australia and under cultural conditions which approximate commercial Cuphea plant production. During the production of the plants, day temperatures ranged from 12° C. to 40° C., night temperatures ranged from 6° C. to 28° C. and light levels ranged from 1,000 to 9,000 foot-candles. Rooted young plants were pinched one time and were four months old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
